Application December 7, 1950, Serial No. 199,625

2 Claims.

This invention relates to cotton pickers, and more particularly to that type of cotton pickers adapted to be handled as a tool and selectively applied to the plant, as desired by the operator.

An object of the invention is to provide an improved cotton picking tool of simple and light construction which can be readily handled and manipulated with oneihand of the operator.

A further object Vof the invention is to provide an improved cotton picking tool in which compressed air from a suitable source is utilized in the tool to set up an induced suction at a nozzle end, whereby the cotton iibers are drawn through the tool and delivered through a suitable conduit connected with the tool to a cotton receptacle or 'collecting bag.

Other objects will more particularly appear in the course of the following detailed description.

The invention consists in the novel construction, arrangement and combinations of parts hereinafter more particularly described and claimed.

One sheet of drawings accompanies this specication as part thereof, in which like reference characters indicate like parts throughout.

In the drawing: y

Figure 1 is a central longitudinal vertical cross section through the improved cotton picker tool;

Figure 2 is a transverse cross section taken on line 2-2 of Figure 1;

Figure 3 is a transverse cross section taken on line 3 3 of Figure 1; and

Figure 4 is a transverse cross section taken on line 4-4 of Figure 1.

In the embodiment of the invention herein illustrated in detail, the improved tool comprises a housing 20, divided longitudinally to provide a tube I and a parallel passage 4I of crescentshaped cross-section positioned about the bottom of the tube. The rear end of the tube is enlarged and exteriorly threaded, as at 2, to accommodate a coupling 3 secured to a exible tube 4 which extends to a cotton collecting bag, not shown.

The opposite or forward end of the tube I is outwardly flared as at 5 and thence bent backwardly as at 6 and inwardly as at 'I to form an annular abutment for the base 9 of a cuplike coupling connection I0 externally threaded, as at I I, to receive a nozzle I2. The base 9 is cut out to surround tube I and provide crescentshaped port I'I on one side, which communicates with the longitudinally extending passageway 4I. At the rear end of tube I is secured by welding, as at 2|', an elliptical plate 2l which extends above the top of housing 20. Parallel to the plate 2l is positioned a second housing plate 22, which housing plate 22 is formed with a flange 26 which is joined to plate 2I and foi-ins a continuation of the passage 4I transversely and around tube I toa control valve having a housing 27 set intosuitable notches formed Yin the plates 2| and 22, this lvalve housing 2l being formed with a chamber 33 through which the valve stem 32 passes and housing a compression spring 34 arranged to contact a transverse abutment 35 formed on the valve stem 32 arranged to normally bias the valve 32' into closed relationship to the valve seat 36. A coupling 3l connects a flexible tube 38 which extends to a suitable source of compressed air adapted to supply to the tool a stream of 'compressed air, indicated generally by the arrows marked A. Valve stem 32 is controlled by a valve control handle H which is formed with a cam face 3I, one end of this lever being pivoted on an upstanding ear 29 formed on the valve housing 2l, as by pin 30. The valve handle H, it will be observed, extends parallel with the tubular housing member I and closely adjacent thereto, intermediate the forwardly positioned nozzle l2 and the rearwardly positioned valve 2l, so that the operators hand grasping the tool will include the handle H and by compression can regulate the supply of compressed air supplied to the tool.

At the forward end of the tool the nozzle I2 is formed with an inwardly turned tubular extension It extending rearwardly and having its inner end contracted into a tapering conical portion I5 which terminates in the restricted port I6 positioned centrally of the tube I, the inwardly tapered portion I5 of the tubular part I4 extending substantially parallel to the outwardly tapering portion 5 of the tube I and forming a fconical annular passage, herein identified as 43. The nozzle I2, by reason of the structure thus described, provides an annular chamber 42 for the compressed air, which as will be apparent, is supplied to it through the passageway 4I, the crescent-shaped port I1, and the annular passage 8 provided between the rearwardly directed portion 6 of the tube I and the flange l0 of the housing plate 9 upon which the nozzle is threaded.

The operation of this improved tool will be readily apparent, the operator grasping it with one hand surrounding the hlandleH and the superposed tubes l and 20, and by opening valve 32 permitting a supply of compressed air to pass from the tubular conduit 38 through the valve, around tube I, through the chamber 25 at the rear end of the device, thence forwardly as indicated by the arrows A into the nozzle from which this compressed air is directed rearwardly through the conical passage 43 into the tube i, thus inducing through the nozzle a suction introducing the cotton fibers and forcing the same rearwardly through tube I, as indicated by the arrows B, and thence through the hose 4 to a cotton collecting bag.

Various changes in the particular details of construction will readily suggest themselves to those skilled in the art, but within the scope of the present invention as claimed.

Having thus fully described my invention, I claim:

1. A cotton picker comprising, a housing divided longitudinally into a tube and a crescentshaped passage, the tube and passage lying parallel to one another, means coupled to one end of said tube to receive picked cotton from said tube, means to supply compressed air to the same end of said passage, the opposite end of said tube being flared, a nozzle connected to said housing adjacent the ared end of said tube, a cylindrical part on said nozzle directed inwardly and having its inward end tapered to form a restricted throat, said cylindrical part posi- 4 tioned with its tapered end within and spaced from the ared end of said tube whereby a conical annular passage communicating with said tube is formed between the tapered end of the cylindrical part of the nozzle and the ilared end of the tube, said nozzle having a chamber surrounding said cylindrical part and having a port communicating with said crescent-shaped passage whereby compressed air from said crescentshaped passage may enter said chamber and be directed rearwardly into said tube through said conical annular passage.

2. En a cotton picker as claimed in claim 1, a Valve to control the flow of compressed air into said crescent-shaped passage, said Valve having an operating handle positioned adiacent said housing whereby the housing and handle may be simultaneously gripped.
